Abstract
A method for estimating a voltage of an input terminal of an inverter includes checking three-phase currents flowing from an inverter to a motor. A voltage of an input terminal of the inverter is calculated based on a plurality of design parameters, the three-phase currents, and PWM duties for determining switching operations of a plurality of switching elements of the inverter.
